This scatter plot visualizes the Iris dataset, showing the relationship between petal length and petal width for three species (setosa, versicolor, and virginica) with points colored by species. The D3 v6 code loads CSV data from a GitHub URL, maps values using linear scales, and renders circles in an SVG. Axes are labeled with rotated text, and the chart employs the `axisLeft` and `axisBottom` functions to display tick marks.
